In order to get a polygonal model based on the scanned data one needs to use the Calibry Nest software.
There are two modes available: Simple Postprocessing and Advanced Postprocessing. The major difference between them is the set of applicable tools. In the Simple mode there are only four buttons available for the user, whereas Advanced Mode offers full functionality.
On the screenshot below the difference between Simple mode tools (in red) and Advanced one is evident.
In the Simple Mode there are only four buttons available for the user:
Open – uploads the .ascan file.
Start – starts finalization of the model with pre-selected settings.
Save – saves the result in one of four available formats: STL, OBJ, WRL, PLY.
Settings – allows to change parameters of post processing (e.g. resolution, etc).
Let’s look at an example:
To begin working with a project you should open it using one of the following methods:
1. Click Open project in the toolbar and select «project file» in the standard dialog box
2. File -> Open menu;
3. Double-click the scan from the list in the Scanner window.
A project tree will be displayed in the Files window.
When all files are successfully uploaded in the software, we select preferred Settings. In the dialog window we choose values for such parameters as hole-filling, resolution, simplification and so on.
When we are done with the settings the next step is to launch finalization by pressing Start. The progress bar on the bottom of the screen is helpful.
The result is a polygonal model. It can be saved in one of four formats: PLY, OBJ, STL, WRL.
The Advanced post-processing in the Calibry Nest software allows to edit the polygonal result with this set of instruments:
To build 3D models of certain objects, it is sometimes necessary to execute several scanning sessions. Most frequently, this is necessary to scan an object from all sides. E.g., scanning an object from above and then turning it over and to scan from below. As a result, it is necessary to assemble the 3D model from several parts.“Multiple” postprocessing is data processing where several scans are used to build a single 3D model. Before running multiple post-procession function for these files, the scans need to be aligned correctly.
If the scan was created using tracking by markers, several scans can be aligned automatically.
After editing is complete, save the whole project or just the polygonal result as STL, OBJ, WRL or PLY. File -> Save project/result as.
